Control device for bicycle and methods

ABSTRACT

A control device wearable by a bicycle rider, the control device including at least one control sensor generating input signals when actuated. A control processor is connected to the at least one control sensor generating control signals responsive to the input signals. A wireless transmitter is in communication with the processor transmitting the control signals and a power source is connected to the shift control processor and the wireless transmitter. The control device may one or more of a control gear changer, one or more suspension component, and other electronically-controllable components or systems.

BACKGROUND OF THE INVENTION

The invention relates to bicycle control systems. In particular, theinvention is directed to systems including wirelessly enabledcontrollers for bicycle gear changers and/or bicycle suspensions andother bicycle components and systems.

Electronic devices and wireless communication are common in modernsociety. Operating such devices during activities which requireconcentration and control such as riding a bike can be hazardous. Thisis because the user input for the control is traditionally mounted tothe handlebar of a bike. In some instances, in well-designedcontrollers, the rider's hands are close to the control switches soactivating the control switches poses little danger. However, in thecase where the rider has their hands in a location remote from thecontrol switches, the rider must then shift one hand to the controlswitch and temporarily control the bike with the remaining hand.Additionally, should the rider wish to operate the control switch whilebraking, the rider would have to remove their hand from the brake leverand temporarily interrupt braking in order to activate the controlswitch.

There exists a need to provide control of remotely operated electronicdevices of a bicycle while allowing the rider to maintain contact withthe bar and a visual line of sight with the road ahead. The presentinvention provides a means of wireless control of multiple deviceswithout the rider changing hand positions on the handlebar.

The prior art controllers typically mount to the handlebar of thebicycle. In U.S. Published Application No. 2008/0168856, shift buttonsare shown integrated with the brake lever assembly and shift buttons aremounted directly to the bar. This requires structure to mount theshifter to the bar which increases weight. Attaching the shifter to thebar requires the user to reach for that particular position to activatea shift. If alternative positions are desired, additional discreteshifters must be attached to the bar. The shifters may all be linked bycables or wires which adds complexity and weight. Alternatively, theymay all be discretely wireless, which requires separate power sourcesfor each device adding weight and complexity.

SUMMARY OF THE INVENTION

According to embodiments of the invention, control devices, which maybeshift control devices, may be carried by/mounted to the user and thusfollow the user to alternative hand positions. A single power source isrequired if all the shifting is done with one hand, and only two if bothhands are used. The shift control devices are easily transportable frombike to bike and only one set is necessary. Additionally, the shiftcontrol devices do not need to be removed from the bar to rechargebecause they are not attached to the bar.

Aspects of the invention contemplate a bicycle shifting system where thefront derailleur and the rear derailleur are controlled wirelessly bymeans of a wireless shift control device or devices located not on thehandlebar but on the rider. In one embodiment, the rider wears the shiftcontrol devices on his/her hands and makes a shift through a specificmovement of the finger or fingers of that hand. Such movements oractuations should not be encountered in the normal course of riding abicycle so as to avoid unintentional shifting.

Some examples of these movements include:

-   -   1. Flicking of the index finger;    -   2. Touching the thumb and any of the other fingers together,        perhaps with some threshold force;    -   3. Hyper-extension of any of the 5 digits beyond the normal        operating range;    -   4. Compression of the tips of the fingers rather than the pads;        and    -   5. Any combinations of the above actions.

Alternatively, the invention contemplates a system with control devicesfor the control of suspension components or systems, or other wirelesslycontrollable components or systems of the bicycle.

The invention also benefits from single-button shifting. Insingle-button shifting, each hand requires one actuator, button, switchor the like connected to the shift control device. For example, aright-hand actuator would cause a shift of the rear derailleur in onedirection, a left-hand actuator would cause a shift of the rearderailleur in the other direction and activating both actuatorssimultaneously would toggle the front derailleur to the other of itscurrent inboard or outboard position.

The invention includes a means to shift the front and rear derailleursof a bicycle from the hands of the rider rather than from the bar of thebike. In this way the user input to control the shift follows the handsand regardless of where they are disposed.

Other embodiments of the invention contemplate positioning the shiftcontrol device on a wearable position other than the gloves of therider. For example, the control device could be attached to othergarments or equipment worn by the rider. In yet another embodiment, thesensor could be a microphone and the commands to initiate the generationof a control signal could be auditory instead of a physical movement.

In some embodiments a battery may be provided to each individual shiftcontrol device to eliminate wires and connectors.

One aspect of the invention is a control device wearable by a bicyclerider, the control device including at least one wearable shift controlsensor generating input signals when actuated. A control processor isprovided in communication with the at least one shift control sensorgenerating control signals responsive to the input signals. A wirelesstransmitter is responsive to the processor for transmitting the controlsignals. A power source is connected to the control processor and thewireless transmitter.

Another aspect of the invention is a shifting system for a bicycle,including a shift control device. The shift control device includes atleast one wearable shift control sensor to generate input signals whenactuated, a shift control processor in communication with the at leastone shift control sensor generating control signals responsive to theinput signals, a wireless transmitter transmitting the control signals,and a power source connected to the shift control processor and thewireless transmitter. The system includes an electromechanical rearderailleur including a rear derailleur wireless receiver receiving thecontrol signals, a rear derailleur motor responsive to the receivedcontrol signals, and a rear derailleur power source connected to therear derailleur wireless receiver and the rear derailleur motor.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the invention will herein be described with reference tothe drawings. It will be understood that the drawings and descriptionsset out herein are provided for illustration only and do not limit theinvention as defined by the claims appended hereto and any and all theirequivalents. For example, the terms “first” and “second,” “front” and“rear,” or “left” and “right” are used for the sake of clarity and notas terms of limitation. Moreover, the terms refer to bicycle mechanismsconventionally mounted to a bicycle and with the bicycle oriented andused in a standard fashion unless otherwise indicated.

FIGS. 1 and 16 show a bicycle 20 having a frame 22 to which a frontwheel 24 and a rear wheel 26 are attached in conventional positions. Ahandlebar 28 is attached near the front of the bicycle 20 and a pair ofbrake actuators 30 is attached to the handlebar. A front derailleur 32may be attached to the frame 22 at or near a front crankset/chainringassembly 34. A rear derailleur 36 is attached to the frame 22 near therear wheel 26. A chain 38 interconnects the front crankset/chainringarrangement 34 and a set of sprockets 40 disposed on and coupled to therear wheel 26.

A prior art shifter 42 is shown in FIG. 2. The shifter 42 is an exampleof a prior art handlebar-mounted electronic shifter. Shifter 42 includesa brake lever 44 with shift buttons 46, 48 attached to the brake lever.The brake lever 44 is mounted to a housing portion 50 of the shifter 42which in turn is mounted to the handlebar 28. If a rider wants toinitiate a shift, the rider's hand must be located either on the housingportion 50 or the bar 28, just below the housing, in order to reach theshift buttons 46, 48. If the rider's hand is located elsewhere, thecontrols will be out of reach and the bicycle cannot be shifted.

FIG. 2 also shows a shift control switch 52 independent of the housing50. This switch 52 may be clamped to the handlebar 28 and provides aseparate location from which the rider can shift the derailleurs.However, in order to have a separate shift location, wires 53 must berun from the primary shift location, or alternatively, the secondaryshift location must have a separate power source, processor, andwireless output means 51, independent of the first location. Thisgreatly complicates setup as wires are typically placed under handlebartape and increases the chance of wire and connector failure as thenumber of shift buttons increases.

FIGS. 3 and 4 show examples of a wireless electromechanical frontderailleur 32 and a wireless electromechanical rear derailleur 36. Inthese examples, the power source 54 for each derailleur device 32, 36may be mounted directly to the device and may be in the form of abattery. Additionally, each device 32, 36 is provided with a wirelesscommunication device 55B (which may include a receiver, a transmitter,or a combination of a receiver and transmitter) in communication with aCPU 56 to enable the devices to wirelessly communicate with a remotetransmitter of a control device such as a shift control device (see FIG.5) or a control device for operating a component or system of thebicycle that is not related to gear shifting, such as a bicyclesuspension component or system. Each of the wireless electromechanicalfront derailleur 32 and a wireless electromechanical rear derailleur 36is provided with an electric motor (not shown) for actuation thereof, asis well-known in the art. Referring to FIG. 16, each of the front andrear suspension systems 86, 88 will include a motor and wirelesscommunication device like that in the above example, but adapted tooperate suspension components of the suspension systems.

Signals transmitted by the control device may include those thatindicate either an upshift or down shift (i.e., a type of controlsignal) for either the front or rear derailleurs 32, 36. The controlsignal may also be a change of state of the suspension system. Thecontrol signal may be transmitted to all derailleur devices 32, 36 orencoded to control one derailleur. Additionally, the transmission may beencrypted to prevent anyone but the transmitter of the signal fromreplicating or recording the signal thereby preventing others fromcontrolling that particular device.

FIG. 5 depicts a glove 58 supporting or serving as a substrate for thecontrol device 57, which includes control sensors 60, 62 at the fingerportions 64 of the glove. The control sensors 60, 62 are connected tointegrated connections 66. The integrated connections 66 connect thesensors 60, 62 to a processor 69, (which may also be known as a controlCPU or control processor), which is any suitable microprocessor capableof generating control signals responsive to input signals from thecontrol sensors. A wireless transmitter 55A is connected to theprocessor 69 for transmitting the control signals. A power source 54powers the processor 69 and transmitter 55A (see FIG. 7).

The processor 69, transmitter 55A and power source 54 of the controldevice 57 may be arranged in a combined form or provided on the glove 58as separate components. The processor 69, transmitter 55A and powersource 54 of the control device 57 may be collectively referred to as anelectronic control unit 68 (ECU). The control device 57 may include anoptional interface 70 by which the electronic control unit 68 can beremoved from the glove, in one embodiment, without the use of tools.

Sensing actions performed by the user with the control device 57 can beaccomplished by various means, as discussed below. The integratedconnections 66 may be wires, conductive fabrics or any conductivematerial or compound running to specific points on each finger andconnected to the ECU 68. As noted above, the electronic control unit 68may include any combination of circuitry, a power source, transmittingand optional receiving devices and a processor (CPU), or the like, whichis programmable with computer code to operate and control the unit forits intended use. Optionally, one of the glove 58 or ECU 68 may includesome form of display or device to generate some feedback which may bevisible or audible, for example (not shown).

The interface 70 may permit detachable mounting of the sensitiveelectronics (ECU 68), so that that glove can be washed, for example.Also the shift control sensors 60, 62 at the fingers of the glove 58 maybe designed to be permanently attached to the glove or may also beremovable to allow cleaning of the glove or to allow the sensors to betransferred from one glove to another. Additionally, the electronics maybe separate from the riding glove 58 itself and be used as a liner,inside of a riding glove, a cover over a riding glove or a deviceattached directly to the rider's hand that connects the shift controlsensors 60, 62 to the fingers and the ECU 68 to the hand, remote fromthe shift control sensors for use without a glove.

FIG. 6 shows control sensors 60, 62 and 72 arranged at the fingers 64 ofa glove 58 according to an embodiment of the invention. In theillustrated example, the sensors 60, 62 and 72 may comprise conductivepads, each arranged at or near each finger portion 64 of the glove.Conductive wires 66 run from the pads to the ECU 68. When the riderbrings two pads into contact, a circuit is closed or the state of thecircuit is changed. In FIG. 6, the index finger and the thumb of therider are touching. This particular contact combination might indicatethat a rear derailleur 36 upshift is desired, and accordingly, willresult in the generation and transmission of a control signal indicativethereof. Likewise, if the thumb and the middle finger are pressedtogether, this might indicate a desired a rear derailleur 36 downshift,and will result in the generation and transmission of a control signalindicative thereof.

One embodiment of an electrical schematic of a wireless communicationsystem 76 responsive to control inputs generated by the glove-mountedcontrol device 57, is shown in FIG. 7. The systems (76, 176, 276)illustrated respectively in FIGS. 7, 11 and 13 each may include anelectromechanical front derailleur 32 and an electromechanical rearderailleur 36, each derailleur including a respective power source 54,CPU 56 and wireless communication device having at least a derailleurwireless receiver 55B. Optionally, the derailleur(s) may be replaced byor provided in addition to one or more suspension components or systems.The ECU 68 includes a power source 54, shift control processor (CPU) 69and wireless transmitter 55A.

In order to avoid unintended shifts, a specific contact time or pressuremay be preset when sensors 60 and/or 62 are actuated. The shift controlprocessor (CPU) 69 can then be programmed to ignore the closed circuitif it occurs for a time less than required or if an input signal occurstoo close in time to a previous input signal. Alternatively, theresistance of the closed circuit can be measured and if the circuit isclosed but the resistance is deemed to be too high, it can be presumedto be an unintended input signal. Thus, the shift control processor 69may be programmed to reject unintended input signals.

Additionally, the system is not limited to shifting only a single devicewith a corresponding single control device 57, as depicted in FIG. 6.The control device 57 can be designed to have only one circuit and thusgenerate only one shift control signal. A right glove with a controldevice 57 might produce a rear derailleur 36 upshift signal and a leftglove with a control device 57 might produce a rear derailleur 36downshift signal. Meanwhile, a separate circuit disposed on either glovemight control the shifting of the front derailleur 32, or alternatively,the front derailleur may be made to toggle from one gear position to thenext by closing both circuits in both gloves at the same time.

FIG. 8 depicts an example of a shift control sensor in the form of aflexible pressure sensitive resistor 78, sold under the trade nameFlexiForce® manufactured and sold by Tekscan. FlexiForce® is apiezo-resistive sensing device in which a resistance is inverselyproportional to an applied force. This type of device may be integratedinto the rider's glove 58 at either the finger pad area (FIG. 9) or thefingertip area (FIG. 10). A schematic of this system is shown in FIG.11. This type of pressure-sensitive switch 78 is very thin and can beeasily integrated into a glove without changing the shape or appearanceof the glove. Also, there are no moving parts, as with a traditionalswitch.

FIG. 11 shows a shifting system 157 including a sensor 78 of the typedescribed above. To operate the sensor 78, the shift control processor69 creates a voltage across the sensor 78. When there is no pressureapplied to the sensor 78, the sensed resistance is relatively highbecause the current passing through the sensor 78 is negligible. When arider desires to shift the bicycle, the rider pushes down on the sensor78. As the force or pressure on the device increases, the resistancedecreases. With a decrease in resistance comes an increase in current.Once the current reaches a predetermined threshold, the shift controlprocessor 69 determines that a shift is desired. The shift controlprocessor 69 is programmed to ignore forces below the predeterminedthreshold, thus avoiding unintended shifts. Optionally, thederailleur(s) may be replaced or provided in addition to one or moresuspension components or systems. In this case the shift controlsystem(s) 157 would shift the state of the one or more suspensioncomponents or systems.

It is understood that the pressure sensitive switch 78 might beconsidered an improvement over individual mechanical switches.Nevertheless, designed correctly, a mechanical switch can yield many ofthe same benefits. Accordingly, the embodiments that include individualmechanical switches located discretely on the fingers of the rider'sgloves are contemplated under the broader aspects of the invention. InFIGS. 9-11, the pressure sensitive switch 78 can be replaced with amechanical switch allowing for changes in mechanical packaging andpossibly other requirement of the switch.

FIG. 12 depicts another embodiment of a control device 257 with shiftcontrol sensors in the form of accelerometers on a glove 58 connected toan ECU 268. Accelerometers are used to measure changes in accelerationand orientation, as commonly used in cell phones and video gamecontrollers. One example of such a device is the ADXL330 low-power, 3axis +/−3G mems accelerometer manufactured by Analog Devices. Suchdevices have many advantages as shift control sensors. They are lowpower, very durable and do not require contact with any other object towork. The sensor simply senses its relative position in space as afunction of gravity and change of position as a function ofacceleration. For example, the orientation of the device relative to theground can be used to indicate a shift signal.

As shown in FIG. 12, the accelerometer 80 is mounted to the back of theindex finger. When the index finger is raised to be horizontal with theground, the sensor assumes an orientation where only one axis of theaccelerometer 80 is subjected to the acceleration force of gravity. Thisis graphically shown in FIGS. 14A-C, wherein the value of accelerationmeasured by the X and Y axis are reversed as the orientation of theaccelerometer 80 changes from a position that is substantially verticalto a position that is substantially horizontal.

An alternative use of the accelerometer 80 is to measure theacceleration imposed on it and set a threshold acceleration beyond whichone can determine that a shift command is desired. This is similar tothe pressure sensitive resistors discussed earlier. Normal ridingactivity imparts forces on the rider's hands from the bicycle whentraveling over road irregularities as well as normal contact forces withthe bars during riding. The CPU 69 may be programmed to only recognizeaccelerations above a predetermined value as an intended shift signal,thereby allowing the rider to generate this value by tapping a finger onthe bar itself with sufficient force. The rapid deceleration of therider's finger upon contacting the bar would be higher than the forcesstemming from the road as these road-induced forces are dampened by theair in the tires and the flexibility of the wheels, frame, stem andbars.

FIG. 13 depicts yet another embodiment of a wireless communicationsystem 276 including a front derailleur 32 and a rear derailleur 36,each including a respective power source 54, CPU 56 and wirelesscommunication device 55B. The shift control device 257 includes an ECU268 and accelerometer sensors 80 connected thereto. The ECU 268 is inwireless communication with the derailleurs 32, 36, as in the aboveexamples.

FIG. 15 depicts yet another embodiment of a wireless control device 357,which may be worn on a rider's helmet 82. In this embodiment, the sensoris a microphone 84 or the like. The helmet also may carry an ECU 368,which may include the same components as in the above examples. Inparticular, the ECU 368 may include a power source, a wirelesstransmitter, and a control processor as detailed above. The controlprocessor of the ECU 368 is configured to receive input signals(generated by voice commands) from the microphone 84 and analyze theinput signals with well-known voice recognition software. The controlprocessor 369 may be configured to generate control signals forcontrolling one or more of a bicycle gear shifting component or system,a suspension component or system or any other controllable components orsystems of the bicycle.

FIG. 16 shows a bicycle that, in addition to the above components, has afront suspension system 86 and an optional rear suspension system 88.Each of the front and rear suspensions 86, 88 will include a motor (notshown) for operating one or more parameters of the system, andelectronic componentry for operating the motor. It will be understoodthat the particulars of the motor and electronic componentry will beadapted in configuration to the intended application, be it a gearchanging device, a suspension device and so on.

In use, and by way of example, in an embodiment where the wirelesscontrol device 357 is used to control a rear suspension component orsystem 88, the control device may be programmed to respond to commandscorresponding to 1) lockout, 2pedal, and 3) open settings of thesuspension. In an embodiment where the wireless control device 357 isused to control a front suspension component or system 86, the controldevice may be programmed to respond to commands corresponding to 1)lockout, 2pedal, and 3) open settings of the suspension. The controldevice 357 could control both the front and rear suspension components86, 88 separately or collectively, wherein a single lockout voicecommand could change both front and rear suspensions to a lockoutsetting simultaneously, for example. In the alternative, the controldevice 357 could be programmed to control the front and rear suspensions86, 88 separately.

In an embodiment where the wireless control device 357 is used tocontrol a wirelessly controllable rear derailleur or rear gear changercomponent or system, the control device may be programmed to respond tocommands corresponding to “up” or “down,” “harder” or easier,” or “one,two, three, four” and so on, for example, to change the gear position ofthe bicycle in single increments. The control device 357 could alsogenerate a shift command to cause a shift of more than one gear positionin response to a single command. For example, the rider could say,“two-up” or “two-down” to change two gear positions up or down. Therider could say, “all-up” or “all-down” to shift the gear changer to oneof the extreme gear positions in one single operation. The controldevice 357 according to the present embodiment could exhibit a broadrange of flexibility and programmability if responsive to voicecommands. In a similar fashion, the control device 357 could be used tocontrol a wirelessly controllable front derailleur.

In a similar fashion, the control device 357 could also be programmed tocontrol other systems (not shown) of the bicycle, such as lights,electrical generators, and other systems such as heart rate monitors,GPS units, power meters, and speedometers, for example, and thecomputerized units that collect, analyze and display data related to thebicycle systems.

In these embodiments, the rider's hands exercise individual control ofone or more derailleurs in a way that does not require that the controldevices be connected to the bike.
